On my machine, `C-h o common-lisp-mode RET` tells me:

    common-lisp-mode is an alias for ‘lisp-mode’ in ‘lisp-mode.el’.

Really?  They're both defined in the same `inf-lisp.el` file.
AFAIK it's a mode that used to be used for a buffer containing
common-lisp REPL running in a subprocess.  I suspect nowadays people use
Slime or SLY which I expect don't use `inf-lisp.el` any more.
Then again, I thought `lisp-mode` wasn't used by those modes either but
I was proved wrong, so maybe they do still use `inferior-lisp-mode`
as well?
